Description

Technical Field

[0001] The invention relates to the technical field of seedling nutrient block production equipment, and in particular to a fully automatic seedling nutrient block production, fertilization and sowing integrated machine. Background Art

[0002] Nutrient blocks are seedling blocks made from basic raw materials such as peat and vermiculite with added slow-release fertilizers, processed agricultural residues and specific adjuvants. They have the advantages of comprehensive nutritional elements, no pathogens or insect eggs, easy operation, seed saving, fast seedling growth after planting and high survival rate. They are an alternative to nutrient pot seedling cultivation.

[0003] The existing fruit, vegetable and flue-cured tobacco seedling raising method is the traditional seedling raising method, which uses plastic seedling raising trays and puts the mixed nutrient soil into the hole trays. The nutrient soil can be ordinary black soil or peat soil. After drying, powder screening, and fertilizer mixing, it is manually loaded into the hole tray, and then the seeds are manually sown into the soil of the hole tray. Some large-scale planting bases use mechanical sowing, but only a small part of the bases, and they cannot be integrated for seedling raising and planting. The traditional seedling raising method consumes a lot of manpower and a large amount of high-quality soil. The planting cost is very high. Now the problem is that there is no one available for the growers and no soil available. In the document (application number: CN202411290117.8), a fertilizing seeder and method for producing seedling nutrient blocks are disclosed. The seeder pours the prepared seedling matrix raw materials into a silo, and the seedling matrix raw materials in the silo enter the lower mold through a spreader; the hydraulic rod is started by a controller, and the telescopic end of the hydraulic rod drives the upper mold to press the seedling matrix raw materials inside the lower mold, which not only replaces the soil-paving hole tray, replaces manual labor, but also replaces the plastic seedling hole tray. However, the equipment can only process one nutrient block at a time, and the production efficiency is low, which cannot meet the demand. Summary of the invention
